Displays the number of reads and writes in the devspaces and in the knltrace file (where the kernel trace is written to) since the last database restart. One access equals a read or write of one page.

To display which thread or process accessed the individual devspaces and for information about the I/O queue of each devspace, choose Display I/O details. This information allows you to recognize I/O bottlenecks. The Queue length and Maximum queue length columns indicate whether there is a large amount of I/O requests queued currently or whether there were a large number of queued requests in the past. To update the display, choose Refresh.
